I have a Creonics issue here, but don't know where to turn. We have a feeder with a 2 axis motion control board made by Creonics. (only using one axis in this machine.) Over the years, we have had to have a board rebooted and/or reprogrammed by the machine mfg due to the watchdog light not coming back on, way too many times. The mfg has been very vague in explaining why this happens and the only resolve is to send them the bad board and $400 (now $460) to have it rebooted. We have done everything they have suggested with filters, isolation transformers and shielding, yet one of these boards still dies for no appearent reason. (Feb/05, June/05, now Nov/05 are the 3 most recent). Prior to this year, the issue has been quiet for about 2.5 years. All in all, these 2 boards have been rebooted probably at least 10 times each over the years.

If any one has any idea what might cause the watchdog light to go out and need rebooting, what is needed to hook up to the board to reset fault(s), where info can be found and/or other info, I'd much appreciate such.

There are 3 boards stacked together. The bottom (main?) board is part number "PC-121-0598". The next board (Thumbwheel expansion) is a "PC-132-0989".

Creonics is now owned by Rockwell (Allen Bradley). When it was still Creonics, the company was located on Etna Road in Lebanon, NH. To the best of my knowledge, there is still an AB office at that location.

If you can find a telephone number for that location, you may be able to speak to someone who can remember back to the Creonics days and help you out.

I have used a lot of Creonics and early AB/Creonics Max controllers. The watchdog timeout is usually caused by a hardware failure, but a poorly designed application program can cause it to timeout also. I still have a few machines using a MAX Control motion controller that is programmed with Accel. I have one machine that was programmed with GML v 3.9.1. The Max control has been virtually bulletproof. We hadn't even had to connect to one in over ten years unitl a few days ago. I found out for sure that Accel and GML 3.9.1 will not communicate when installed with windows 2000. We have an old win95 laptop stashed away for this very reason.

A/B bought Creonics and put their wrapper on its Max Control calling it the S-Class IMC. Over the years they've changed the firmware may times and added features etc. Most of what A/B has done is okay, but they screwed up the auto tune function, which works very well in a Max Control, but is virtually useless in S-Class and 1394 controllers. A/B did make the controllers much easier to communicate with and troubleshoot with the introduction of GML and GML Commander. (Commander does not support the older Max Controls.)

You can still find a lot of help by calling AB tech support. I have even gotten them to send me manuals that are not available on the web.

Does the motion controller have a name on it? I don't recognize the part numbers you listed. What you have must be even older than my antiques. You will be much better off if you upgraded to something more modern. You can replace most any motion controller with a controllogix processor and it's analog motion control card(s).

Only because I'm suspicious of things I can not see, I sometimes wonder if they programmed in something to shut it down or forgot to program in something to prevent something mike a counter or math regester from over flowing.

One person at the mfg says they have someone else reprogram the board. Another told me on the last one that they do it and that they can not tell me how to reset the board because they have to burn into the eeprom. Odly enough, these boards come back with the last set length still in them, Tells me that the program is not lost, at least entirely. I know I could easily demo such behavour with one one of our SLC500 here, just that I'd have a flashing a CPU fault indicator instead of turning off the watch dog light.

I also have been wondering, seeimg the last guy told me they burn the eeprom, why these 2 Creonics cards can not be rebooted each time at power up from the eeprom, like my SCLs do in some cases. Only thing changed for settings in the Creonics, is the length.

You mentioned GML and ??? and hooking up to your Max boards. Is there anything there that I can handle or acquire? The mfg of this machine was going to set us up with a cable and software and assistance, so that I could reboot these in house, then after about 3 more boards ($1200), backed out with the story that someone else does that programming for them. To begin with, they tried to scare me off with DOS based software stories, but I'm not too unfamilliar with DOS. (I didn't let that go of that until Win 95 was out and use DOS regurlarly to this day.)

I was using Creonics products back when those boards were designed. Your refeference to SAM-EX MCC triggered a memory of a DOS program called SAMLINK that was used to program Creonics motion controllers. I'll see if I still have a copy of it and if there any help files associated with it.

As I recall they were a decent motion controller, although somewhat limited. In fact one of my favorite application stories involves a Creonics motion controller at a plant in Appleton Wisconsin.

The application called for a transfer mechanism that had to stop at a position that depended on the length of the product it was moving. The length was entered from an HMI panel and affected quite a few settings on the machine. The particular model of motion controller only had a limited number of ways to enter a target move position. You could enter it with a two-digit thumbwheel or you you could use the thumbwheel to pick one of 99 predefined moves. Neither of those options worked for us. We pretty much had to be able to let an operator pick a random value anywhere in the range that the mechanism could cover. So we came up with a creative solution. We programmed a BASIC module in the PLC to send a sequence of ASCII commands to the motion controller's serial port.

Stop execution of the motion controller program.
Put the motion controller into edit mode.
Jump to line xxx of the program.
Edit line xxx with the new target position.
Exit edit mode.
Restrt the motion controller program.

Essentially, it was one computer reprogramming another.

Anyway, if I can find a working copy of the SAMLINK program, I'll be in touch. I think that SAMLINK is nothing more than a dumb terminal program like hyperterminal. If the help files exist, they may give you an idea of the command set to program the thing.

Well, I found my Creonics files including SAMLINK and EASYMCL. SAMLINK is a file upload/download program. EASYMCL is the editor for creating motion programs. Unfortunately the help file for EASYMCL doesn't include a list of the available commands, so it looks like you'll need to get your hands on the manual for the unit you have. If you can get the manuals for your motion controller and it uses the Creonics MCL language, then these programs may be of some help to you. If so, I'll be happy to send you a copy. My recollection is that you didn't have to purchase the software. It was included when you bought the controller.

Of course, your problem may not be in the motion controller. It might be in the amplifier (drive) portion. If that is the case, you may have no recourse but to continue to send it back to the factory to be reset.

The application I mentioned was installed at Appleton Papers back in 1988. It was on their folio sheeter for carbonless paper. I have no idea if they are still using the machine, and if so, if it still has the Creonics motion controllers. I haven't had any communication with them for at least ten years, maybe longer. The last contact I had was with a guy named Kevin Sargalis. Kevin worked with me at the company that built the machine and eventually took a position with Appleton Papers. It may be worth making a few phone calls to Appleton Papers to see if their maintenance peole have any documentation on Creonics motion controllers of the same vintage as yours. Good luck.

I have one of these boards that I must do something with today. The watchdog went out on this board the other day. I hooked up my old laptop to it last night and got in and found some parameters that must have reset to defaults. I went into the spare working board, did a capture of text and then set the bad board to match the working one. Appearently I missed something, as this board does not work, even though the WD light comes on. Once enabled, after a few moments, I get a fault and the WD shuts off. I'm going to try and locate info I missed.

For now, my question is as follows.

I have the Access software to configure this board. It has APPLINK, which I should be able to receive the whole application then send that application to another board. When I try to receive, I get an error, stating "time out" and MCC failed to respond. I communicate in terminal mode just fine. Any ideas on what may be preventing receiving the application from thes eboards?

Update. Found a few items I missed the first time through, while comparing settings in good board to bad board. I did not check/edit the GAINS and the Velocity settings. Edited those to match, and away we go.

Still interested in any info pertaining to receiving whole application info from a good board, so that I have a back up of the whole kaboodle available and thus make it easier/faster to restore in the future. I'm sure this machine will be upgraded, replaced and/or a similar second line installed, somewhere down the line, but given the fact that these boards loosing their parameters periodically, there's no other problems with the system.

If you intend to troubleshoot the Max Control, you will need the correct programming software and the original application.

The units I worked with were programmed using a DOS program called Accel. Some later firmwares allowed programming using early versions of GML (after Allen Bradley took over).

THe last time I needed a manual, I was able to get it from an Allen-Bradley support technician. It was not on their knowbase or anywhere on the web, but the guy emailed it to me after a lengthy phone call.

That was at my previous employer, so I don't still have a copy.

I do know that the old books have been scanned into .pdf files and you can get them if you can get ahold of the right people on the phone.

Creonics motion controllers were very reliable, just not too easy to troubleshoot. The eventually evolved into the Allen-Bradley S-Class motion controllers which were much less reliable, but much more user friendly.

About the only problems we ever had were power supplies and motors/cables. Once in a great while the app would get corrupted if we didn't have the memory protect jumper correctly installed.

I have used a lot of Creonics and early AB/Creonics Max controllers. The watchdog timeout is usually caused by a hardware failure, but a poorly designed application program can cause it to timeout also. I still have a few machines using a MAX Control motion controller that is programmed with Accel. I have one machine that was programmed with GML v 3.9.1. The Max control has been virtually bulletproof. We hadn't even had to connect to one in over ten years unitl a few days ago. I found out for sure that Accel and GML 3.9.1 will not communicate when installed with windows 2000. We have an old win95 laptop stashed away for this very reason.

How to set Transducer Counts/Mtr Rev and Motor type for Drive/Motor 1394 configuration in GML 3.9.1 (IMC 1394 S Class Compact,4100-234-RL)? The motor is Lenze MCA21X17 with 2048PPR TTL Encoder (A,A not,B,B not and Z,Z not).

Working from memory, look under axis configuration. There should be tabs for each of those details you mention. As for the setup in the amp, I think you will need to choose a kW size that meets or exceeds the motor, and custom adjust its current limits also but I think it should work.

I used 1394 systems with A/B resolver motors in most cases, but we did use them with encoder feedback too. IIRC, they had two choices for encoder voltage, 5v and 24v (this may be an s-class memory).

__________________It's not all the variables I am most concerned with, it's the undiscovered constants.

Not GML Commander. I used GML 3.9.1.
In my old program, someone set the Counts/Mtr Rev 10000 or 8192 or else. the encoder is 1024 PPR actually. But the program works,why?
